| 摘 要： | CMYK减色成色体系中,黑版的加入及总墨量的不同会影响设备的颜色输出能力。利用自己开发的工具软件和色彩管理技术,从设备的ICC特性文件入手,求解了输出设备的三维色域体。比较了黑版产生、不同的产生方式,以及不同的总墨量限制下设备可输出的色域。结果表明,加入黑版后设备在暗色调的输出色域得到扩展;总墨量限制相同时,不同的黑版产生方式主要影响分色结果,对色域几乎没有影响;允许的总墨量大时,输出的色域则大,体现在暗色调区域颜色的增多,从380%到320%的总墨量变化,可造成暗色调2个单位的明度增加;而340%到320%的总墨量变化,色域差异则不明显。

| Abstract: | In CMYK subtractive color system,the application of black plate and the amount of total ink will have an influence on the output devices' color performance.By utilizing the software and color management technology developed by ourselves,a three-dimensional model of the output device was calculated based on the device's ICC profile and the color gamut with different black production methods,and different total ink amounts were compared.As the results demonstrate,the output color gamut in the low tonal range ... |
